Specification of Letters Patent.

Patented (lot. 9, 191?.

Application filed July 19, 1916, Serial No. 110,009. Renewed August 27,1917. Serial No. 188,492.

To all whom it may concern:

Be it known that I, CALVIN B. PATCH, a citizen of the United States,residing at -Glenellyn, in the county of Dupage and Stateof Illinois,have invented a certain new and useful Improvement in Yokes, of whichthe following is a full, clear, concise, and exact description,reference being had to the accompanying drawings, forming a part of'this specification.

sectional view of the structure illustrated in Fig. 1 and taken on thebroken line 2--2 A thereof. Fig. 3 is a front end elevation of theimproved'yoke; Fig. 4 is-a transverse,

vertical section taken on the line 4& of Fig.

11). And Fig. 5 is a perspective of the locking lock.

In said drawing, the improved yoke is des ignated generally by thereference A and 10 denotes the draw bar, the latter having the usualupper and lower shoulders 11 and 12. The yoke A, as shown, comprises anupper arm 13, lower arm 14:, rear connecting piece 15, and a hoodedforward end, the latter comprising side walls 1616, top wall 17,

i and downwardly oifset bottom wall 18, the

latter merging into the lower arm 14:, as clearly illustrated in Fig. 1.The top wall- 17 is provided on its inner side with a transverseshoulder or gib 19 which engages the upper shoulder 11 of the draw bar.The side I walls 16-16 are provided with angular raped slots 20 throughwhich may be inserted transversely, a locking block B. The locking blockB is of substantially angular cross-section and has an upstanding flange21 which'cotiperates 'with the lower shoulder 12 of the draw bar, and ahorizontal flange 22. The side walls of the hood are prefer ablyprovided with reinforcements or shoulders 23 on their inner faces toform a better backing for the locking block whenthe lat date the head 26of the bolt so that the latter,

after it has been inserted through the rectangular opening 24, may beslipped forwardly to the position most clearlyindicated in Fig. 1. Theinner face of the bottom wall 18 is counter-sunk as indicated, at 28 toreceive'the head of the bolt when in the position shown in Fig. 1. Andsmall shoulders 29 are provided, which prevent the head of the bolt fromslipping rearwardly after it has been seated in the counter-sink 28. Thebolt is held in position by the nut 30 and cotter 31.

As will be apparent from an inspection of Figs. 1 and at, thecounter-sink 28 is relatively shallow so that a portion of the bolt headwill extend up abovethe top surface of the lower wall 18 and hence belocated partly within the slot 27 formed in the under-face of the blockB. By this means, the block B is prevented from lateral movement as willbe apparent.

In the preceding description, it will be seen that the expedient which Ihave provided for retaining the block B in position, is simple andinexpensive and the bolt may be insertedandremoved with ease. Inaddition to the foregoing, it unnecessary to e; tend the block Bbeyor.=.: the side walls of the hood, thus providing for thoseconditions in railway service where the space between the front stops iscomparatively narrow. Furthermore, by making the openings 20 in the-sidewalls somewhat larger than the sec tion of the block B, it is apparentthat, by first removing thebolt, the block B may be shifted laterallysufiiciently to clear one side of the hood, and then twisted andwithdrawn from the forward end of the hood. After this has been done, itis apparent that the draw bar may be dropped down and removed from theyoke without disturbing the latteror the gear therewithin.

me zeee I claim:

it A yoke for draf riggings having at hooded forward end Within which isadapted to he received a shouldered drew her butt, a removableshouldered locking block associated with said hood and adapted toengegea shoulder of the draw butt, the bottom Wall of the hood having anopening therein, and a short bolt having its head insertihle throughsaid opening and to engage said locking block to prevent the latter frombeing displaced.

2. A yoke for draft formed its forward end to receive a draw bar outttherewithin, a rel'novehle looking block adapted to engage a shoulder onthe drew her, one Wall of said end of the yoke having a slot therein,one portion of the slot being enlarged to permitthe insertion of bolthead t-herethrougl1,.the locking block heiiig provided with a slotarranged to aline -with said bolt slot, and a bolt insertlble throughthe slot therefor and having portion of its head located Within the slotin the block, when the bolt is in operative position.

3. A yoke for draft riggings having a hooded forward end Within which isadapted to be received a drew her butt, the hottom Wall of said hoodedend being provided with a "f-shapedslot, e shouldered locking blockinsertihle laterally through slots in the side "Walls of the hooded d,and means insertible through said T-Sl' slot in. the hooded end andadapted, when in position, to engage the under-face lockingblock andprevent shifting thereof. l. yoke for draft riggings having a hollowhood et its front end, the top wall of said hood being rovided with i tthe upper shoulder of a oriu butt, shouldered looking tr-loclr.insortihle through the side walls'of said hood and erronged to engagethe lower sho of drew her butt and a short holt iosor through the bottomwall of said hood the head of Said bolt, When the letter in opera.- tiveposition, being located Within a slot on -the underfece of the block. 7

In Witness that I claim the foregoing have hereunto subscribed my name15th day of July, 1916.
